I would suggest that you configure the GRE tunnel enpoints with an IP address that is not use pref a /30 will do.

Hi Andrew,

Thax for reply.

1. I am sending the attachment with diagram.Here i am having 2 same networks in my cloud.

2. So for one existing lan n/w of R5 we r advertising as it is & for my new lan n/w which of R4 i create a tunnel in bet R1 & R4 whether it is possible to work or not pls confirm.

Yes it is possible - you just create a GRE tunnel with the source & destination's of the tunnel as the IP addresses of the serial interfaces, Give the tunnel itself a /30 IP address (not being used anywhere else) then configure either a dynamic routing protocol or static routes.

Thax Andrew,

i will try.
